-3/8p=9 how do you isolate p?
LenKa [72]

Answer:

multiply both sides by 8 then divide by -3

or in one step divide both sides by (-3/8) which is the same as multiplying by

(-8/3)...

-3p = 72

p = -24

Step-by-step explanation:

{( \sqrt{ {2}^{2}  +  {4}^{2} } )}^{2}  =  \\  = ( \sqrt{4 + 16} ) {}^{2}  =  \\  =  {( \sqrt{20)} }^{2}  =  20

(Drinking and driving.) Just after Eric had his last drink, the alcohol level in his bloodstream was 0.20 (milligram of alcohol

Here's the formula for exponential decay:

A = p(1-k)^t

(where A = new amount, p = principal (starting) amount, k = rate of decay, and t = time)

Let's use what we know and fill in the expression.

0.08 = 0.20(1-0.47)^t

And now we solve for t.

0.08 = 0.20(0.53)^t \\ 0.4 = 0.53^t \\ log0.4=t*log0.53 \\ t = \frac{log0.4}{log0.53} = \boxed{1.44\ hours}

Answer:

a) 0.6032

b)

Lower limit: 0.48

Upper limit: 0.72

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

Question a:

In a random sample of 63 professional actors, it was found that 38 were extroverts.

We use this to find the sample proportion, which is the point estimate for p. So

\pi = \frac{38}{63} = 0.6032

Question b:

Sample of 63 means that n = 63

95% confidence level

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6032 - 1.96\sqrt{\frac{0.6032*0.3968}{63}} = 0.4824

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6032 + 1.96\sqrt{\frac{0.6032*0.3968}{63}} = 0.724

Rounding to two decimal places:

Lower limit: 0.48

Upper limit: 0.72
